    Abstract: A method for generating a two-dimensional radio coverage map comprising a plurality of physical levels including a first physical level and a second physical level. The access point is located above the second physical level. A first radio coverage map comprising original points located at a first distance from the access point is generated. Each of the original points has a first predicted value. A distance is selected to place the two-dimensional radio coverage map at the target distance from the access point. Coordinates of map points of the two-dimensional radio coverage map are generated. Each of the map points corresponds to one of the original points. An offset value representing an attenuation due to the target distance being different than the first distance is computed. For each of the map points, a predicted received signal strength value is generated by adding the offset value to the first predicted value of the corresponding one of the original points.

    Abstract: Systems and methods are disclosed for determining the floors on which APs are located for WiFi-based indoor positioning systems. A data collection phase is followed by a data analysis phase. During data collection, measurement data to observed APs may be collected from various locations on different floors. The measurements data may include received signal strength indication (RSSI), optional round-trip-time (RTT) data to the APs, and floor information of the measurement locations. Measurement data may also be collected from crowd sourced data without floor information of the measurement locations. In data analysis, the collected measurement data are analyzed using various algorithms to determine if APs belong to the same floor and to assign APs on the same floor to the same cluster. APs on different floors may thus be assigned to different clusters. If the floor information of the measurement locations is known, each cluster may be assigned a floor number.

    Abstract: Various methods, apparatuses and articles of manufacture are provided for use by one or more electronic devices to detect and/or respond to certain changes (anomalies) within a wireless signaling environment. For example, a first electronic device may receive a report of a threshold anomaly detected by a monitoring device deployed at a fixed predetermined position within a coverage area of a network service device, and may initiate an investigation by requesting that a second electronic device attempt to monitor certain transmissions of and/or actively communicate with a network service device. In response to a determination based, at least in part, on the investigation that the threshold anomaly represents a threshold change in status within the wireless signaling environment, the first electronic device may transmit a status report regarding the wireless signaling environment to another electronic device.

    Abstract: Systems, apparatus and methods in a mobile device for saving power by powering down all transceivers not carry traffic are presented. The traffic may be voice and/or data traffic. A mobile device may select single transceiver to carry voice traffic and the same or different transceiver to carry data traffic. A mobile device first determines its position (e.g., a coarse position estimate) then consults a database or map to determine which networks are theoretically available. The mobile device executes a rule against the theoretically available networks to select the single network, then enables the transceiver for the one network to determine if the network is actually available for use. If the database inaccurately states a network is available from a current position but the transceiver shows that the network is actually not actually available, a next network from the database or map and corresponding transceiver are selected.
